Overview
The following information has been assembled to aid in the conversion from a Bitzer
Horizontal Screw Compressor to a Fusheng BSR Compressor.
For replacement compressor selection, a capacity comparison of each compressor is given in
table 1 and dimension information is given in table 2.
The suction and discharge connection sizes are different between the Bitzer CS and Fusheng BSR
compressors. Size information is given in table 2
The Fusheng BSR compressors are supplied with suction and discharge service valves and an
internal check valve. The weight of the compressors are similar and listed in table 2
On the Fusheng BSR thermal motor protector and discharge temperature, the control circuit is
wired through terminal PTC to INT96FYS 1 and 2.
The reverse phase and oil switch protector is wired through terminals 11 and 14, and module
power is connected to L and N.
The loading and unloading between the compressors is very similar.

Fusheng - BSR INT69FSY Wring Diagram
The Fusheng INT69FSY Diagnose automatically saves operational and error data in a non-volatile
memory. This data can be retrieved on PC and analyzed for diagnosis.
Each module is pre-wired inside the terminal box. The module monitors discharge gas/oil temperature
by a PTC sensor. The module also monitors motor winding temperature by the motor sensors
embedded into the motor windings which are wired in series and connected to the module. Phase
sequence control for direction of rotation is also monitored.
The following connections should be checked for tightness.
Voltage / Phase Connections:
• L1 Connected to connection on terminal plate 1
• L2 Connected to connection on terminal plate 2
20
• L3 Connected to connection on terminal plate 3
Motor Winding (R1)/Discharge Gas (R2) Temperature Connections:
Module number 1 connected to R1 (Motor Winding thermistor)/R2 (Discharge Gas thermistor) to
number 2 on module.
Compressor Control Circuit is wired through terminal 11 and 14.
